Figure 2 is anelevation looking towards the discharge end ofthe nozzle.

Figure 3 is a fragmentary view in longltudina'l section illustrating theshut-od or closure valve.

Figure 4 'is a section on line if-d Figure 3.

Figure 5 is a top plan view of the nozzle.

'llhe nozzle includes a tubular stem part l and a tapered tubulardischarge part 2 disposed at right angles to and of less length thanpart i. rlhe outer end of part 2 is formed with an inwardly extendingannular flange 3 having a beveled inner face to provide -a valve seat d.lhe part l has its outer periphery at one end formed with threads 5 andis shown' as having coupled to its other end a fluid feed line 6. Theline 6 is flexible. Formed integrally with; the inner end of' end part 2is an elbow coupling 8 having one q leg thereof indicated at Qthreadedlyengagl ing with the threads 5 of part 1 and itspotlier leg indicated atintegral with the inner end of part 2. The coupling 8, in alignment withleg 10 is formed with a lateral extension 11 provided with a reducedperipherally threaded outer end l1 which forms a peripheral shoulder 12provided with an inclined socket 13 having its wall threaded. rl`he eX-tension 11 is formed with an axial bore let opening into coupling 8. Thereduced end 11 of extension 11 has a cupv shaped edge 14 to receive apacking 15. A flanged sleeve 15 threadedly engages with the reduced end11 of extension 11 to maintain the packing 15 in position. The elements11, 15 and 15 provide a stung box for seating a valve stem to behereinafter referred to.

The tubular discharge part 2 is formed of an inner andan outer section2, 2 respectively which tlireadedly engage with each other. The section2 can be removed when the valve seat l becomes impaired and a newsection 2 substituted, or section 2 can be removed to replace thecontrolling valve to be presently referred to. Section 2 preferably isof less length than section 2".

Fixed to the stem part 1 in proximity to that end of the latter to whichis coupled the line 6 is a bracket 16 curving towards the extension 11and terminating in an arm 17 of circular cross section. The arm 17 isfixed at one end to bracket 16 and inclines outwardly from such endtowards its other end. r1`he arm 17 opposes the stem part 1 and projectsbeyond that end of part 1 which is secured to coupling 8. Secured at oneend in socket 13 and projecting from extension 11 is an inclined support18 which is anchored at its outer end to the arm 17.

`Normally engaging the seat l for the purpose of closing the dischargeend of part 2 is a shutoff or closing valve 19 acting to close thenozzle after the desired quantity of fluid has been dispensed. As thevalve is positioned to close the discharge end of the nozzle drippingsfrom the latter is prevented. The arrangement also enables the nozzle tobe immediately removed from the filling intake of a tank or receptaclewhen it is shut-off as the attendant does not have to hold the nozzle inthe intake for flow of drippings as is the case at present whendispensing gasoline at a service station.

The valve 19 has a beveled edge, its inner side formed with a tubularextension to provide a socket 204and an inwardly extending yoke 21integral with such side. The yoke 21 has an opening 22 and passingtliroughthe latter, abutting the tubular extension and extending intosocket is a valve stem 23 which is detachably connected to yoke 21 by aremovable pin 24. rl`he valve 19 is loosely connected to stem 23.

rlie stem 23 is provided with an abutment 25 and a series of radiallydisposed guide igeeaa arms 26 interposed between yoke 21 and abutment25. The stem 23 is of a length to extend through and project vbeyond theouter end of bore 14. Surrounding the stem 23 and' interposed betweenabutment 25 and the inner face of coupling 8 is a coiled controllingspi-'ing 27 for the valve 19. The spring 27 normally retains valve 19against seat fl and acts to shift valve 19 to shut-o position when ashifting mechanism for the stem is released.

rllhe shifting mechanism for valve stem 23 includes a pair of oppositelydisposed handle members 28, 29 of semi-cylindrical cross section. T hemember 28 is attached at one end to the arm 17 by a band 30 which isiiredly secured in position by lioldfast means 31. The member 28 isinterposed between stem part 1 and arm 17. The clamp 30 is arranged inproximity to bracket 16. The member 28 is resilient, normally disposedparallel to stein part 1 and of a length to project beyond sleeve 15.The member 28 normally seats against sleeve 15 and is formed with anopening 31 for the passage of stem 23, the latter is formed with threadson its outer end 32. Nuts 33 engage with end 32 of stem 23 forconnecting the latter to member 28.

The handle member 29 is arranged outwardly with respect to arm 17 and isformed with a pair of apertured ears 34. Carried by the outer end of arm17 and connected to ears 3e is a pivot 35 for member 29 and which alsoconnects the latter to arm 17. The member 29 projects beyond the outerend of arm 17 and has its outer end connected to the outer end of member28 by a headed bolt 36 and a nut 37. The outer ends of members 28 and29, are apertured as at 38 andr extending therethrough is the shank ofbolt 36. lnterposed between the outer ends of members 28 and 29 andcarried by bolt 36 is a coiled spring 39 acting to normally hold suchends in spaced relation. The members 2.8 and 29 provide a compound leverto provide satisfactory control in operating the opening and closing ofvalve 19. l

Carried by member 28 is a pivoted latch 4.0 capable of engaging with theinner end of member 29 for latching it in position to retain valve 19shifted from off its seat. 'lihe member 28 carries a hook 49 forsuspending the nozzle when not in use.`

When the .nozzle is used, the operator or attendant grips the members 28and 29 and shifts member 29 on its pivot and applies pressure to saidmember 28 and owing to the connection between the outer ends of saidmembers, member 29 acts to shift the outer end of member 28 towards arm17 thereby carrying stem 23 therewith and unseating valve 19 against theaction of springs 27 and 39. Member 29 can then be latched if desiredfor the necessaryperiod. -When pressure is relieved upon member 29 orthe latter uiil?? `latched thevalve 19 will immediately seat itselfl toclose the nozzle at the discharge end of the latter.
